Far to early to tell.
Destiny and Deep Down look the most interesting and could have potential to be "1000+ of gametime" games.
I will surely play a lot of the WoW and D3 Addon and so will i still play DayZ and will try out Wildstar.
The Division looks interesting too and so does DriveClub.And of course the yearly Fifa which i don't count cause i usually play over 1000 OnlineGames before the year ends.
